A total of 79 Salmonella spp. were isolated from Pusan area in 2000. The serotypes of 79 Salmonella isolates were classified as 42 strains of S. typhi(53.1%), 24 strains of S. enteritidis(30.4%), 9 strains of S. montevideo(11.4%), 2 strains of S. typhimurium(2.5%), 1 strain of S. infantis(1.3%) and 1 strain of S. indiana(1.3%) strains(16.5%) of Salmonella sp. were isolated at May July, respectively. The isolates of S. typhi were sensitive to most sntibiotics except streptomycin. All isolates of S. typhi were especially sensitive to tobramycin, gentamicin, colistin, kanamycin, samikacin, sulfamethozazole/ trimethoprim, cefriaxone, ceftazdime, cifrofloxacin, cefoxitin and cefotaxime. Isolates of S. enteritidis wer presented higher resistance than isolates of S. typhi. Twenty-four strains of S. enteritidis were sensitive to kanamycin, amikacin cifrofloxacin, cefoxitin and cefotaxime, however 13 strains(54.2%) of S. enteritidis were resistant to carbenicillin, ampicillin and ticarcillin. Nine strains of S. montevideo were sensitive to most antibiotics except carbenicillin and streptomycin. Each 1 stain of S. indiana and S. infantis was sensitive to most antibiotics used in this study except streptomycin. Three kinds of resistant pattern (CB, SM, TE, AM, TC). In the case of S. enteritidis isolates, 9 kinds resistant pattern were detected. Most frequent resistant pattern of S. enteritidis isolates was CB, AM, TC type(16.7%)

To clarify the clinical utility of the calvarial bone graft in the maxillofacial reconstruction, we performed on anatomical study by measuring the regional thickness of the parietal bone on 17 Korean adult dry skulls. Before the sectioning the calvarium, the anatomical landmarks were marked on each specimens. And then we measured the total thickness of the parietal bone, the thickness of the outer and inner cortical plates on various points in each sections of parietal bones using a digital caliper under the stereomicroscope. The total thickness of the parietal bone was ranged from 5.17mm to 7.50mm, and there were no statistical difference in the total thickness of the parietal bone on the same points bilaterally. But there was a tendency that the thickness of the parietal bone was thicker toward to the lambda point than the coronal suture area. At the other hand, the thickness of the outer and inner plate of the parietal bone was the thickest at the first point of the right aspect on the line 1, the first point of the left aspect on the line 5, respectively. In conclusion, this study showed that the donor site of the parietal bone for the maxillofacial reconstruction should be located at more posterior and medial area of the parietal bone than the prevalent known donor site.

The prefabrication by vascular induction into random patterned flaps is a method creating axial donor flap by implantation of nourishing pedicles prior to harvesting random patterned flaps. The purpose of this study was to evaluate the viability of a thin prefabricated flap prepared by the subdermal implantation of fasciovascular pedicles without subcutaneous tissue or muscular layer, by comparing with the prefabrication by the subpanniculus carnosus implantation of vascular pedicles, which is well known to a predictable survival rate by many authors. In the left abdomen of 40 Sprague-Dawley rats, the fasciovascular pedicles were implanted in the subdermal layer in group I(n=20) and sub panniculus carnosus layer in group II(n=20), respectively. 5 weeks later, 4 x 6 cm sized abdominal flap was elevated with implanted vascular pedicle as an island and reposed immediately. At the same time, in the right abdomen, conventional island flap was elevated and reposed. After 3 days later, the evaluation of the survival area was carried out in each side, in both groups. The mean proportions of the survival areas in group I were 74.2 and 91.8% in the prefabricated and conventional flap, respectively. And those in group II were 76.4 and 91.2% in the prefabricated and conventional flap, respectively. These results showed that there is no difference in the proportion of survival area between two types of prefabrication. In conclusion, it is possible to prefabricate a thin axial-patterned fascioutaneous flap without subcutaneous tissue and the viability of this prefabricated flap is reliable as much as that of other prefabricated flaps having subcutaneous or muscular tissue.
약수터수로부터 분리한 Yersinia enterocolitica의 성장특성 및 Plasmid 유형

The studies were conducted to explore the dffects of growth or survival against various factors and plasmid profiles of 49 Y. enterocolitica isolated from springs water. In the presence of calcium hypochlorite, y. enterocolitica was entirely extinguished by exposure for 33 hours at 0.8 ppm concentration, and was grown up to 7% NaCl, but not at 95 NaCI. Y. enterocolitica was presented optimal growth at pH 7.0 anad 9.0, and not allowth the growth at pH3.0, 5.0 and 11.0. The optimal temperature for growth of Y. enterocolitica was 25$\circ$C and 35$\circ$C, and allowed the growth at refrigerant temperature, 5$\circ$C. Y. enterocolitica was remarkably decreased by exposure for 30 seconds under UV light, and entirely extinguished by exposure for 90 seconds. Therefore, UV light was effective for sterilization of Y. enterocolitica. Fourty-nine strains of Y. enterocolitica were harbor plasmid DNA of approximately 46 Kb molecular weight.
